When using the wizard to print envelopes, Epson printer (WF 3640) with center feed rear slot will not print. This is similar to HP and other printers reported. Generally, the envelope is ejected and a letter feed from the letter paper supply is printed upon (when new doc is selected, envelope invoked and text inserted for envelope only). With some adjustment of characteristics as described for other brands, a "paper mismatch" message is generated and no printing takes place.
